What command would you use to display the current working directory?

The command used to display the current working directory in a Linux system is pwd, which stands for "print working directory." When executed, this command outputs the full path of the directory that the user is currently in. It is an essential command for users to understand their location within the file system hierarchy.

The other options serve different purposes. The cd command is used to change the current directory. The ls command lists the contents of the current directory, showing files and folders, but does not indicate the path of the current directory. Lastly, the dir command, while it can be used to list directory contents as well, operates more similarly to ls and may not be present in all Linux distributions, particularly those that are more minimalist. Understanding the specific functions of these commands helps users navigate and utilize the Linux command line effectively.
